| Thanks Poppy, but now that I think about it I will use a Sullivan cable on my next RC conversion. Sadly, I have not been flying for at least 2 months as I picked up a second job that averaged an extra 25 hours a week. Now that that is over I am back to building again and am keeping my eye on the weather reports so I can find a good time to dust off my transmitter. |

| Nice work! I like the innoative amd scale tailwheel operation. Most would have chosen to hook wheel to rudder, thus ruining the scale appearance. How is flying the trainers coming along? You should be the old pro by now. |

| I find that flying gets a little boring unless the plane is tail heavy which adds a touch of excitement. ;-) The CG right now is about where Guillow's suggests for FF. And since I have removed wing incidence I'm not sure how much I should trust their CG location for rudder only RC control. I guess I won't know for sure till the maiden flight. |

| tail heavy is bad, very, very bad |

| Looking at all that empty space between the motor and battery made me think about the balance point so I bolted on the wing and checked it out. It balances about 1/8" aft of what Guillow's recommends for R/C. Once I had the wing on I couldn't resist the temptation to drive it around the floor a bit to test out the steering, which I am happy to say worked quite well. |

The weight of the fuselage is 5.5 oz with all electronics. I estimate the weight before covering to be around 8 oz. I wanted a AUW of 10oz (~70 watts/lb) but had hoped to get 7-8oz. Unless I do some serious wood removal I'll be closer to 10oz AUW. |

I went with the pull-pull setup to the tail wheel and a push rod to the rudder and elevator. Most of this gets covered as is and will require cutting into the covering if a repair or adjustment is needed. |

I haven't quite figured out yet how to best link up the rear wheel as the little arm for it moves not just in the X-Y plane but also a little in the Z plane. My best ideas so far are to either use an elastic material or a pull-pull. |

The motor is mounted and stringers are starting to go on. If you look close you can see push rods for the rudder and elevator. |

I finally got around to fixing the tail wheel. I used 1/32" plywood for the support which will hopefully be strong enough without adding too much weight. |

| Before you do anything drastic (X-Acto blade, anyone?) a possible fix as is, would be to cut a notch at the top of the brass sleeve, facing forward. If the wire for the wheel can be easily bent, it could be bent forward, looking like the tiller of a boat with movement restricted by the notch. This could also be done at the bottom with a kink made just above where the tire slips into the sleeve. Just thinkin'. |

| If you really want a feel for life on sailing ships in the Royal Navy (and many other navies, I'm sure), the Master and Commander series of books are excellent. "Master and Commander" and "Far Side of the World" were turned into the pretty good movie with Russell Crow. But the books really describe fitting out a ship for a cruise, the sounds and smells. Really informative and entertaining. |

| The ideal situation would be to have the sleeve perpendicular when the plane is resting on the ground, which is what I thought I had when I applied the epoxy without really thinking it through properly. But since I could aim for vertical and inadvertently have a slight aft angle yet again, I would rather aim for a slight forward angle. The wheel only has to turn a few degrees in either direction as needed to navigate the runway, so a mild forward angle should not be problematic. |

| They sure are (the bottom two), I actually started reading the one in the middle by Harold Hahn. The first half of the book is strictly history and much of that in the form of letters to and from the British Admiralty. It is interesting to see how and why a spirit of independence grew in the colonies and that there was actually hostile actions against British ships as early as 1764 (if not earlier). |

| Steve, do you want the tailwheel to freely rotate? If so, you will probably want the brass sleeve to be perpendicular to the ground. If the sleeve cants forward (currently, it is canted to the back)I think it will still be somewhat unstable as you taxi on the ground. I'll bet a couple of piece of balsa with corresponding holes, attached to the framework will get you what you need. |

| Hey! These look like books about SHIPS!!!???? ;) |

| Glad to hear, I hope the struggle with the USPS was worth it. |

| Great! The DR 1 was finally delivered yesterday!! |

Sometimes I forget that I work a 3 minute walk from a 6 story library with 1.4 million books that will loan them to me for 3 months. No need to mail me the book now DD, I can read this copy and don't have to return it till December 8th. |
